No, I think he means the
animation, not the code
In RenX, there is a little slider bar along the bottom of the screen. Set it to the first frame (far left) and then click the 'animate' (possibly called 'record') button. Then, set the slider to the next frame and move your objects slightly towards where you want them to be when the animtion is finished. Repeat for the next frame, etc. etc. You do not have to use all the defualt 100 frames
Once you are finished, export as w3d as 'Hierarchical Animated Model' (with the right number of frames set in the boxes)
I'm sure someone else will be able to give you a better explanation if you wait a while
EDIT: Took too long to write...
